Crop nitrogen is an efficient index for estimating crop yield. Using hyperspectral information to monitor in cotton real time can help guide cultivation. In this study, we used drip-irrigation Xinjiang as the research object and employed various treatments explore correlation between vegetation indexes leaf concentration (LNC) canopy density (CND) of different growth periods interannual. We 30 ...

Perception of photoperiod changes enables plants to flower under optimum conditions for survival. We used doubled haploid populations of crosses among Avalon × Cadenza, Charger × Badger and Spark × Rialto and identified short-day flowering time response quantitative trait loci (QTL) on wheat chromosomes 1BS and 1BL. We used synteny between Brachypodium distachyon and wheat to identify potential...

As distinct from the cereal crops and the spring-flowering fruits, which are characterized by a reproductive climax, cotton is like the tomato and cucurbits in its indeterminate growth; but it is different in the minor extent to which fruit size is influenced by environment and fruitfulness. In a regional variety study (3), 16 varieties of cotton planted during each of three years at eight loca...

We model the evolution of flowering time using a multilocus quantitative genetic model with non-selective assortative mating and mutation to investigate incipient allochronic speciation in a finite population. For quantitative characters with evolutionary parameters satisfying empirical observations and two approximate inequalities that we derived, disjunct clusters in the population flowering ...

As temperature is a common regulator of temperate plant phenology, future increases in global temperatures are likely to cause shifts in the timing of plant phenophases such as flowering and senescence, with potential feedbacks on species interactions and carbon cycling. We used a 3-year field warming study in a temperate grassland to investigate the effects of two levels of warming (þ;1.58C an...

Effects of photoperiod on development, survival, feeding, and oviposition of boll weevils, Anthonomus grandis grandis Boheman, were assessed under five different photophases (24, 14, 12, 10, and 0 h) at a constant 27 degrees C temperature and 65% RH in the laboratory. Analyses of our results detected positive relationships between photoperiod and puncturing (mean numbers of oviposition and feed...

Bt hybrid cotton was significantly benefitted by the soil application of Sagarika sea weed extract granules at 25 kg ha-1 yr-1 along with recommended basal fertilizers dose or foliar nano ZnO 4% 0.04% squaring and flowering stages. These treatments enriched index leaf residual P Zn content beyond 20 μg g-1 fresh weight during boll development stage this resulted in significant improvement lint ...

An alternative means by which to examine the importance of assimilates supply to flower and pod formation is to analyze the relationships of leaf area index (LAI), above-ground dry matter (ADM), leaf area duration (LAD) and crop growth rate (CGR) around flowering with flower number and pod/flower ratio. For this objective, an experiment was conducted at Agricultural Research Station of Gonbad, ...
