TL;DR: Plant height and number of leaves were not directly but indirectly statistically significant to yield of green biomass and varied from insignificant and very weak to sporadically medium strong and statistically significant.
Abstract: Objective of the research were phenotypic and genetic correlation
coefficients of three species of Sorghum genus - forage sorghum S. bicolor
Moench. (genotype NS-Džin), Sudan grass S. sudanense L. (genotype Zora) and
interspecies hybrid S. bicolor x S. sudanense (genotype Siloking). Studies
were carried out on samples of plant material from the first cut. The
following morphological-productive traits were studied: plant height, number
of leaves per plant, mass of leaves on the stem, average stem mass and yield
of green biomass. In the analysis of genetic and phenotypic coefficients,
differences depending on the impact on studied morphological-productive
traits are observed. The highest value of the stem height was recorded in
Sudan grass (2.281 m), as well as number of leaves per plants (7.917). The
greatest mass of leaves per plant was established in forage sorghum (49.05
g), and the highest average stem mass was recorded in interspecies hybrid
plants (80.798 g). Variation of morphological-productive indicators per
species was significant and very significant. Coefficients of simple
correlations indicate the presence of very strong to almost complete,
statistically very significant positive correlations, so these effects were
expected. Plant height and number of leaves were not directly but indirectly
statistically significant to yield of green biomass and varied from
insignificant and very weak to sporadically medium strong and statistically
significant. [Projekat Ministarstva nauke Republike Srbije, br. TR 31078]

TL;DR: In this article, the effects of lime and zinc levels, as well as their interaction on development in castor bean plants, were evaluated under greenhouse conditions without temperature control, in pots with 17 dm3 of "dystrophic Red Latosol", medium texture.
Abstract: The objective in this work was to evaluate the effects of lime and zinc levels, as well as their interaction on development in castor bean plants. The hypothesis of this work is that the lime levels reduce the zinc availability in soil for the plant. The experiment was carried out under greenhouse conditions without temperature control, in pots with 17 dm3 of 'dystrophic Red Latosol', medium texture. The statistical design was of randomized blocks, in a 3 x 5 factorial scheme, with four replicates. The treatments consisted of liming to reach three basis saturations: 40, 60 and 80%, combined with five zinc levels: 0.5, 1.0, 2.0, 4.0 and 8.0 mg dm-3. Only one plant per pot was grown up to 174 days after emergence (first mature raceme), at which point the morphologic and production components of plants were evaluated. Higher lime levels resulted in greater number of seeds per plant and dry matter of seeds per plant. There was interaction of basis saturation and zinc in plant height, in dry matter of root and in length of raceme (masculine part and total). However, none of these increases reflected a significant difference in weight of 100 castor bean seeds.

TL;DR: To reduce lodging susceptibility due to overly slender stems and to achieve about 95% of maximum yield, the proper population range for kenaf forage harvested at 89 d after sowing would appear to be 343,500 to 637,000 plants ha -1 .
Abstract: Population density can affect kenaf (Hibiscus cannabinus L.) forage morphology, yield, and nutritive value. The impact of plant population density on dry matter (DM) yield, DM partitioning in aerial organs, and forage quality parameters such as crude protein (CP), acid detergent fiber (ADF), and neutral detergent fiber (NDF) was determined. This study was conducted in Matamoros, Coahuila, Mexico, in the summers (June-September) of 2005 and 2006. Kenaf response to six plant population densities, ranging from 160,000 to 1,860,000 plants ha -1 , was determined using a randomized complete block design with four replications. Regression analysis was used to examine the relationship between plant density and parameters measured. Response of DM yield to population density was quadratic with maximum production (7078-7469 kg ha -1 ) between 920,000 and 1,245,000 plants ha -1 . Dry matter yields per plant, number of nodes, and stem diameter declined as population density increased in a quadratic fashion, primarily between 160,000 and 840,000 plants ha -1 . Dry matter partitioning into aerial organs and nutritive value were not affected by plant population. To reduce lodging susceptibility due to overly slender stems and to achieve about 95% of maximum yield, the proper population range for kenaf forage harvested at 89 d after sowing would appear to be 343,500 to 637,000 plants ha -1 .

TL;DR: This is the first report of stomata on fruits of Rosa, which seem to be normal in appearance and usually few, scattered, mostly on the upper part of fruit, and open or closed.
Abstract: Achenes of 36 species representing all subgenera and sections of the genus Rosa were studied. All have stomata on the pericarp that seem to be normal in appearance. They are usually few, scattered, mostly on the upper part of fruit, and open or closed. This is the first report of stomata on fruits of Rosa.
