a study of the susceptibility of chickpea (cicer arietinum l.) seed varieties to mechanical damage
نویسندگان
چکیده
mechanical damages inflicted upon seeds in harvesting, handling and further subsequent processes are worth attention because they unfavourably influence the quality of seed. seed damage results in lower grain value, storage problems, and reduced seed germination and seedling vigor, resulting in a subsequent diminishing yield of future crops. the present experiments were conducted to determine the extent of mechanical damage to chickpea seeds (physical damage along with reduction in percent germination) due to impact. a completely randomized factorial design of three replications was employed for each combination of variables. independent variables were consisted of chickpea seed varierty (arman, bivanij, filip93-93, hashem and ilc482) and impact velocity (10, 20 and 30 m/s). it was found out that chickpea seed variety and impact velocity had significant effects on percentage of seed damage (p=0.01). with increasing the impact velocity from 10 to 30 m/s, the percentage of seed damage increased from 17.79 to 87.57% (72.61% physical damage and 14.96% reduction in germination). physical damage to seeds at impact velocities higher than 10 m/s was higher than damage from reduction in the germination rate. it was observed that the filip93-93 chickpea seeds were more susceptible to mechanical damage than other varieties and had 63.81% total damage (48.72% physical damage and 15.09% reduce in germination) and the arman chickpea seeds had the lower total damage (35.47% physical damage and 11.66% reduce in germination).

GENETIC DIVERGENCE IN CHICKPEA (Cicer arietinum L.)
Genetic diversity of 27 chickpea genotypes was studied through Mahalanobis D and Principal Component analysis. The genotypes under study fall into five clusters. The cluster II contained the highest number of genotypes (11) and Cluster I contained the lowest. Cluster I produced the highest mean value for number of pods per plant. The inter cluster distances were much higher than the intra clust...

متن کاملDissecting the Root Nodule Transcriptome of Chickpea (Cicer arietinum L.)
A hallmark trait of chickpea (Cicer arietinum L.), like other legumes, is the capability to convert atmospheric nitrogen (N2) into ammonia (NH3) in symbiotic association with Mesorhizobium ciceri. However, the complexity of molecular networks associated with the dynamics of nodule development in chickpea need to be analyzed in depth. Hence, in order to gain insights into the chickpea nodule dev...

The seeds of ten different genotypes of chickpea (Cicer arietinum L.) originated from Egypt, ICARDA and Saudi Arabia, were used to screen their tissue culture response on various media combination. MS media supplemented with 1, 2 and 4 mg of each of IBA and transzeatin /l, were tested. The results showed that stem results were far better from leaves explants. The callus induction ranged from 6....

Photoperiod is one of the major environmental factors determining time to flower initiation and first flower appearance in plants. In chickpea, photoperiod sensitivity, expressed as delayed to flower under short days (SD) as compared to long days (LD), may change with the growth stage of the crop. Photoperiod-sensitive and -insensitive phases were identified by experiments in which individual p...
