The research was intended to analyse the response of five papaya varieties to phosphorus fertilization in tidal swamp areas. The research was conducted at the Peatland Project (PLG) in Mentangai, Kapuas, Central Kalimantan, from August 2007 to April 2008. A split plot design was used. The main plot had the following P application: 100; 200; 300 g P/plant, and the subplot had the following varieties of papaya: Bt1; Bt2; Bt3; Bt4; Bt7. There were 3 replications and 10 plants per unit of treatment. The observed parameters were: (1) vegetative growth (plant height, stem diameter, internode number); (2) and fruit quality (fruit number, fruit weight, fruit length, fruit circumference, flesh thickness, and total soluble solid). The research result showed that four of five papaya varieties, namely Bt1, Bt2, Bt4, and Bt7 proved to have a higher growth and production response than Bt3. Therefore, the four varieties Bt1, Bt2, Bt4, and Bt7, show good prospects for development in the tidal swamp areas. P application affected significantly plant height only, but did not have an effect on other parameters of plant growth and fruiting. These findings could be used as a guide for choosing varieties suitable for cultivation in the tidal swamp areas.

Effects of prohexadione-calcium (ProCa, 125 and 250 mgL–1) and ProCa + ammonium sulfate (AMS, 500 mgL–1) treatments on vegetative characteristics (shoot growth, branch diameter, trunk cross-sectional area (TCSA), canopy volume, number of flower per cm2, number of fruits per cm2) and quality parameters (fruit size, flesh firmness, color, titratable acidity and soluble solids content (SSC)) of ‘0900 Ziraat’ sweet cherry were investigated in this study. Solutions were sprayed when the shoots were just 10 cm long in 2014 and 2015. As compared to control, in 2015, TCSA decreased only with ProCa treatments (125 and 250 mgL–1) and canopy volume and shoot length decreased with all treatments. On the other hand, number of flower and fruit per cm2 significantly increased with all treatments. While there were not significant differences in fruit size, flesh firmness, color, SSC and titratable acidity values were significantly lower in 250 mgL–1 ProCa and 250 mgL–1 ProCa + AMS treatments. It was concluded that ProCa treatments could be used as an efficient tool for suppression of shoot growth and to increase the number of flower and fruits per cm2 in ‘0900 Ziraat’ sweet cherry cultivar.

Barley stripe mosaic virus (BSMV) is an established and extensively used virus-induced gene silencing (VIGS) vector for gene function analysis in monocots. However, the phenotypes generated by targeted gene silencing may be affected or masked by symptoms of BSMV infection. To better understand the potential effects of BSMV-VIGS in hulless barley (Hordeum vulgare var. nudum), the accumulation pattern of BSMV and its impacts on vegetative growth and water status were investigated. The results indicated that the vegetative growth of infected plants was significantly and continuously impacted by BSMV from 10 to 40 days post inoculation (dpi). When the accumulation of BSMV was extremely high (7 to 11 dpi), infected plants displayed twisted leaf tips with an increased water lose rate (WLR) and decreased water content (WC). Virus accumulation declined and stabilized after 25 dpi, at this stage, the WLR and WC were unaffected in the infected plants. The efficiency of VIGS was tested by the silencing of Phytoene desaturase (PDS). RT-qPCR indicated that BSMV-VIGS can be sustained with good efficiency for up to 40 dpi under an altered condition with lower temperature (22 ±1°C) and higher relative humidity (70 ±10%). It was concluded that 25 to 40 dpi was the appropriate time zone for drought-related gene analysis by BSMV-VIGS under such condition.

In recent years, biofertilisers have emerged as a promising component of an integrated nutrient supply system in agriculture. The objective of this study was to examine the influence of selected biofertilisers on the vegetative growth, the content of N, P2O5 and K2O in the leaves and stems, and on the physiological parameters of pepper of the variety of ‘Sofiiska Kapiya’ cultivated under organic agriculture conditions. This experiment was carried out from 2009 to 2011 on the experimental fields of the Agroecological Centre at the Agricultural University-Plovdiv (Bulgaria), situated on the territory of a certified ecological farm. The study included the following biofertilisers – Boneprot, Lumbrical, Baikal EM “Effective Microorganisms”, Emosan, and Bio One. The results of the biometric measurements of the average plant height at the end of the vegetative period showed the highest values for the variant treated with Emosan on the Boneprot basic fertilisation (62.60 cm – 2009; 64.80 cm – 2010, and 63.87 cm – 2011). Upon feeding with the biofertilisers Emosan and Baikal EM on basic fertilisation with Boneprot (2009, 2010 and 2011) at the pepper mass fruit yield stage, plants showed higher values of net photosynthesis (PN) that were also similar to the high values observed in the flower bud stage. The highest intensity of transpiration (ȿ) was observed for the variants treated with the biofertilisers Baikal EM (2009 and 2011) and Emosan (2010) on basic fertilisation with Boneprot. It was concluded that the feeding with Emosan stimulated the vegetative growth of the pepper plants due to the high concentrations of nutrient-providing proteins contained in this biofertiliser. The results showed that biofertilisers do not significantly impact the P content of the pepper leaves and stems, but changes were more obvious in the leaves. The fertilisation with the studied biofertilisers increased the K2O content in leaves and stems compared to the control (non-fertilised) plants; the values were higher for the leaves.

MADS-box genes encode transcription factors in all eukaryotic organisms thus far studied. Plant MADS-box proteins contain a DNA-binding (M), an intervening (I), a Keratin-like (K) and a C-terminal C-domain, thus plant MADS-box proteins are of the MIKC type. In higher plants most of the well-characterized genes are involved in floral development. They control the transition from vegetative to generative growth and determine inflorescence meristem identity. They specify floral organ identity as outlined in the ABC model of floral development. Moreover, in Antirrhinum majus the MADS-box gene products DEF/GLO and PLE control cell proliferation in the developing flower bud. In this species the DEF/GLO and the SQUA proteins form a ternary complex which determines the overall "Bauplan" of the flower. Phylogenetic reconstructions of MADS-box sequences obtained from ferns, gymno- sperms and higher eudicots reveal that, although ferns possess already MIKC type genes, these are not orthologous to the well characterized MADS-box genes from gym- nosperms or angiosperms. Putative orthologs of floral homeotic B- and C-function genes have been identified in different gymnosperms suggesting that these genes evolved some 300-400 million years ago. Both gymnosperms and angiosperms also contain a hitherto unknown sister clade of the B-genes, which we termed Bsister. A novel hypothesis will be described suggesting that B and Bsister might be involved in sex determination of male and female reproductive organs, respectively.

Salt stress is known as one of the most severe abiotic factors limiting the plant production all over the world. In this study, three additives: (i) supplemental Ca (5 mmol L–1) to nutrient solution, (ii) foliar application of micronutrients (Fe, Mn and Zn at 60, 160 and 110 mg L–1, respectively), and (iii) combination of both of them were evaluated aiming to reduce the negative impact of salt stress on tomato plants cultivated in a soilless culture and improve the internal quality of fruits. The obtained results show that salinity reduced vegetative growth and physiological parameters, fruit yield and its components, and even more lowered fruit market classification of tomatoes. Salinity treatment reduced most of essential macro- and micronutrients in tomato fruit, whilst Na content was increased. Tomato productivity and fruit quality were ameliorated under saline conditions by increasing Ca into nutrient solution and applying a foliar application of micronutrients. A combination of both additives ranked the first to alleviate the adverse effects of salinity on tomatoes, followed by solo supplemental Ca into saline nutrient solution. On the other hand, the internal fruit quality of antioxidant compounds, such as vitamin C, lycopene, α-carotene, β-carotene and lutein as well as acidity, total soluble solid and dry matter percent, were increased under saline conditions.

In this experiment, early ripening plum trees were pruned at two different times. The experiment was conducted at the Fruit Experimental Station in Samotwór near Wroc ław in 2001-2004. Objects of the study were 8 year-old plum trees of 'Herman', 'Cacanska Rana', 'Sanctus Hubertus' and 'Cacanska Lepotica' cultivars budded on 'Myrobalan' seedlings (Prunus divaricata). The experiment was established in a randomised block design in three replications with 6 trees per plot. In 2001-2003, time of tree pruning was differentiated. Half of the trees were pruned only at the end of August (summer pruning after harvest of fruit). The other pruning took place at the end of March (dormant pruning before blooming time). Time of pruning had no influence on vegetative growth and chemical composition of leaves. No matter what the time of pruning, the total sugars, reducing sugars, potassium, calcium, magnesium and phosphorus contents in leaves were similar. Sugars, calcium and phosphorus contents were significantly influenced by the year. Foliar nutrient content differed according to the plum cultivar. 'Sanctus Hubertus' showed markedly lower leaf K and Mg contents, whereas 'Cacanska Lepotica' had a higher P content. Pruning time had an influence on the crop efficiency index. Dormant-pruned trees were significantly more productive.

A field experiment was carried out during 2017–2018 in the Horticulture Research Station farm in El Kanater El Khayreia, El Kalubeia Governorate, Egypt, to find out the response of foliar application of melatonin, GA3 and NAA on vegetative and fruit attributes of ‘Canino’ apricot. Different plant growth regulators influenced all variable parameters related to vegetative growth and fruit. Results revealed that between all growth regulators, the foliar application of melatonin following by GA3 there was the highest vegetative growth as compared to other treatments, while GA3 gave the highest yield following by melatonin as compared to other treatments. Treatment with NAA improved vegetative growth, yield and fruit quality to a lesser extent as compared to the control.
