Little biochemical information is available on carbohydrate metabolism in developing canola (Brassica napus L.) silique (pod) wall and seed tissues. This research examines the carbohydrate contents and sucrose (Suc) metabolic enzyme activities in different aged silique wall and seed tissues during oil filling. The silique wall partitioned photosynthate into Suc over starch and predominantly acc...

four rapeseed cultivars (hayola 401, hayola 308, rgs and option) were evaluated for some physiological traits under stress (50 % field capacity (fc) and non-stress (irrigated) conditions. the factorial set of treatments was arranged within a randomized complete block design with three replications. the collected data were analyzed using path and factor analyses. these is results showed that bas...

Seeds per silique (SS), seed weight (SW), and silique length (SL) are important determinant traits of seed yield potential in rapeseed (Brassica napus L.), and are controlled by naturally occurring quantitative trait loci (QTLs). Mapping QTLs to narrow chromosomal regions provides an effective means of characterizing the genetic basis of these complex traits. Orychophragmus violaceus is a cruci...

Oilseed rape (Brassica napus) characteristically has high N uptake efficiency and low N utilization efficiency (NUtE, seed yield/shoot N accumulation). Determining the NUtE phenotype of various genotypes in different growth conditions is a way of finding target traits to improve oilseed rape NUtE. The aim of this study was to compare oilseed rape genotypes grown on contrasting N supply rates in...

A higher level of fertilizers can have negative effects on the environment; therefore, selection environmentally friendly preparations to increase plant productivity is very important. The aim this study was evaluate effect exogenously applied amino acids L-proline (30 mM L-1) and L-glutamic acid (1.5 M winter rapeseed (Brassica napus L. subsp. oleifera (Delile) Sinskaya) measuring number siliq...

This paper reviewed the effects of insect pollination on yield parameters plants from family Brassicaceae presenting different breeding systems. Meta-analysis indicates that in both self-compatible and self-incompatible crop species, meta-analysis seed (Y), silique set (SQS), number siliquae/plant (NSQ), seeds/silique (NSSQ) increase when are insect-pollinated compared to there is no pollinatio...

Acetyl-coenzyme A (acetyl-CoA) formed within the plastid is the precursor for the biosynthesis of fatty acids and, through them, a range of important biomolecules. The source of acetyl-CoA in the plastid is not known, but two enzymes are thought to be involved: acetyl-CoA synthetase and plastidic pyruvate dehydrogenase. To determine the importance of these two enzymes in synthesizing acetyl-CoA...

Accumulation of dry matter in siliqua, number of siliqua per plant, length of siliqua and seeds per siliqua of rapeseed (Brassica campestris L.) plants were studied under three irrigation levels (no irrigation, one irrigation at 30 DAS and two irrigations at 30 and 60 DAS) and three row spacing (20 cm, 30 cm and 40 cm). Th e experiment was carried out at Sher-e-Bangla Agricultural University (S...
