Leaf Size Recognition and Evaluation of Some Attelabid Weevils (2) Apoderus Balteatus

AbstractA leaf choice experiment was conducted and the behaviour of the female weevil was observed before she commenced cutting. The female always performed a sequence of stereotype behaviours preceding cutting. The results of this study indicate that the female firstly decides the number of eggs to be laid in the cradle and then starts looking for a leaf suitable for that number of eggs. While the female is making a cradle, she measures and perceives for different purposes three different distances on the leaf (or something that represents each of them: 1) the length of the whole leaf, i.e. the criterion of adequacy of a leaf for a cradle, 2) the leaf width, i.e. the criterion of adequacy of a leaf for a two-egg cradle, and 3) about 1 cm along the main vein from the leaf base, i. e. the determinant of the cutting site. These three are probably measured while the female is performing the stereotype walking. Measuring both leaf length and leaf width amounts to predicting the shape and the size of the cradle.

A complete diallel cross involving four experimental strains and six standard cultivars of Indian mustard. Brassica juncea (L.) Czern. and Coss., was investigated for the inheritance of leaf length and leaf width. Considerable heterosis and heterobeltiosis were found in certain hybrid combinations for both characters. Several crosses exceeded the performance of the best cultivar. Partial dominance for leaf length and overdominance for leaf width were observed. Highly significant additive gene effects were found for both characters bur only about one third of the total variance exhibited by leaf length and about one sixth of that by leaf width may be ascribed to this component. The correlation between the two characters was positive. It was concluded that breeding programs should put more emphasis on leaf length rather than leaf width for effective manipulations of leaf size.

Leaf Parameters

Sixteen morphophysiological parameters of horticultural importance were investigated in 82 anthurium accessions grown in the Caribbean. The spathe colors included red, pink, white, green, orange, purple, coral, and brown and obake types with red, pink, and white spathe colors accounting for 63.4% of the accessions. There was wider variation in spadix color combinations than spathe color. There was wide variation for the cut flower and leaf parameters evaluated with productivity and peduncle length having the smallest and largest range, respectively. The frequency distributions were skewed to the right for spathe length, spathe width, spathe size, spadix length, spadix diameter, leaf width, leaf size, and productivity and was normal for leaf length, spadix angle, peduncle length, petiole length, and spathe showiness. Accessions with wider leaves had longer leaves and longer petioles; those with longer spathes had wider spathes; and those with longer peduncles had correspondingly longer petioles. Peduncle length also showed moderate, weak correlations with other leaf measurements and spathe parameters, respectively. Spadix diameter showed moderate correlations with leaf parameters. Spathe showiness showed moderate, weak correlations with spathe measurements and productivity, respectively. Principal component analysis of the 13 quantitative parameters showed that the first three principal components explained 75% of the variation in the accessions. Leaf length, leaf width, leaf size, petiole length, peduncle length, and spadix diameter; spathe length, spathe width, spathe size, and spathe showiness; and productivity loaded on the first, second, and third component, respectively. Hence, one leaf and one spathe size parameter, spathe showiness, petiole length, peduncle length, spadix length, spadix angle, spadix diameter, and productivity as well as spathe, spadix, peduncle, and petiole colors can be used as descriptors for anthurium. Based on these results and market information, an Anthurium ideotype adapted to the humid tropics is described.

Plant Habit

Considerable diversity exists in Capsicum L. germplasm for fruit and leaf shape, size, and color as well as plant habit. Using F1, F2, and backcross generations developed from diverse parental stocks, this report describes the inheritance patterns and relationships between unique foliar characters and diverse fruit and plant habit attributes. Our results demonstrate that pepper fruit color, shape, and fruit per cluster were simply inherited with modifying gene action. Broad-sense heritability for fruit color and shape and fruit per cluster was high, whereas narrow-sense heritability for these characters was moderate to low. Although fruit clustering was simply inherited, the number of fruit per cluster exhibited a quantitative mode of inheritance. High fruit counts per cluster were linked with red fruit color and anthocyanin pigmented foliage. Fruit shape was linked with immature fruit color and inherited independently of mature fruit color. Leaf color, length, and plant height were quantitatively inherited. Leaf shape did not vary, but leaf length varied and was positively correlated with leaf width. Broad-sense heritability for leaf characters, including leaf length, leaf width, and leaf color, was high. With the exception of leaf width, which exhibited low narrow-sense heritability, high narrow-sense heritability for leaf characters denoted additive gene action. Plant height displayed high broad-sense heritability. Moderate narrow-sense heritability suggested that additive effects also influence plant height. Analysis of segregating populations demonstrated that red and orange fruit color can be combined with all possible leaf colors from green to black. These results provide new data to clarify and extend available information on the inheritance of Capsicum fruit attributes and provide new information on the genetic control of leaf characters and plant habit.

Descriptive Statistical Analysis

Seeds need favorable environmental conditions to germinate but sometimes these conditions are not available. The goal of this work was to evaluate the influence of different concentrations of NaCl on in vitro germination and development of Capsicum annuum seedlings. The experiment was conducted at the Laboratório de Biotecnologia Vegetal at Centro de Ciências Agrárias (CCA) of Universidade Federal da Paraíba (UFPB), Areia, PB, Brazil. Ornamental pepper seeds (Capsicum annuum L.) were submitted to five concentrations of NaCl: 0, 25, 50, 75 and 100 mM. The experimental design was completely randomized, with five treatments and seven replicates, each replicate consisted of one flask with one seed. After 14 days in vitro, the germinated seedlings were characterized for seedling height, hypocotyl width, cotyledon leaf length, cotyledon leaf width, leaf number, radicle length, fresh matter and germination. The data were submitted to analysis of variance by the F test ( p ≤ 0.05). When significant differences were detected, the data were submitted to regression analysis. Percentage of abnormal plantlets was also calculated and submitted to descriptive statistical analysis. The percentage of germination was not affected by the NaCl concentrations used in this work. However 75 e 100 mM salt concentrations influenced the cotyledonary leaf width, total fresh matter and percentage of abnormal seedlings.

An experiment was carried out using eight double cross F1s (DCF1s) as lines and two testers to obtain sixteen Line ×Tester hybrids for the evaluation of major growth and flowering traits thereby to understand the breeding potentiality of the parental lines. The performance of growth and flowering traits of all twenty-six genotypes were evaluated in a randomized complete block design (RCBD) with three replications. The analysis of variance (ANOVA) showed all the genotypes were significantly different for all agro-morphological traits under study. The estimated general combining ability (GCA) effects showed that parent 5(P5), were superior for plant height, stem diameter, number of leaves, leaf length, days to flowering and attitude of floral axis followed by parent 2(P2) for leaf length, leaf width, days to flowering and attitude of floral axis and parent7 (P7) for number of flower, flower diameter, bud length and attitude for floral axis. Likewise; tester 1 found to be best combiner with significant GCA effect for almost all growth and flowering traits (except number of leaves). The plant height, leaf width, number of flower and attitude of floral axis showed prevailing additive gene action while stem diameter, number of leaves, leaf length, days to flowering, flower diameter and bud length indicated predominance of dominance gene action. We can conclude that parent P5, parent P2 and parent P7 can be used as good mother lines and the tester 1, as good donor for the seed production. SAARC J. Agri., 17(1): 175-187 (2019)
