one of the main problems in the mass production of pepper transplant is the stickiness of seed coat to the cotyledony leaves that can lead to no emergence or having poor emergence of pepper seedlings. therefore, in order to evaluate the effects of different sowing depths and soil compactions on emergence and early seedlings growth of pepper, a greenhouse experiment was conducted in the faculty ...

Albino seedlings that arise during seed reproduction can have a significant impact on plant growth and breeding. In this research, we present the first report of albino occurrences in process Prunus salicina describe cytological, physiological, transcriptomic changes observed seedlings. The which were several plum cultivars exhibited abnormal chloroplast ultrastructure perturbed stomatal struct...

Plants are exposed to antibiotics produced by soil microorganisms, but little is known about their responses at the transcriptional level. Likewise, few endogenous mechanisms of antibiotic resistance have been reported. The Arabidopsis thaliana ATP Binding Cassette (ABC) transporter AtWBC19 (ABCG19) is known to confer kanamycin resistance, but the exact mechanism of resistance is not well under...

The grasshopper is found all the year round. It is considered as a pest for seedlings. The consumption index differed significantly between groups fed on different diets. Mated females consume more food than virgin females or virgin males. The highest values were recorded for the bean seedlings fed groups indicating some inadequacy in the nutritional value of bean. The growth rate was the highe...

The objective of the study was to evaluate biometry fruits and seeds S. punicea in order determine point collection for production seedlings species. were collected from plants situ Barra do Ribeiro, RS. In laboratory, they separated by staining in: stage 1, 2 3. Fruits measured with digital caliper (mm), counting number locules. At each water content, seed dry matter germination test evaluated...

Auxin flows in a polar manner to target tissues and exert its morphogenic effect. Preventing auxin movement, with polar auxin transport (PAT) inhibitors, or increasing auxin levels in tissues through exogenous application can provide a means for assessing the importance of appropriate tissue distribution and concentration of this hormone during development. The formulation of culture media for ...

Characteristic rapid death of pines after infection by Bursaphelenchus xylophilus suggests the involvement of phytotoxins in the pine wilt disease syndrome. Crude extract from diseased pine is toxic to pine seedlings, whereas an extract from healthy pine is not. The response of seedlings to the crude toxin is more prominent in susceptible pine species than in resistant ones. Benzoic acid, catec...
