Shoot-root traits of broccoli (Brassica oleracea var. italica L.) as influenced by different irrigation schedules
Frequency of irrigation to the crops is the key factor for proper growth and economic yield. Therefore, in the current study growth of broccoli plants was investigated under different irrigation levels in pot culture condition. Five levels of irrigation schedules were applied including I0 [Non-irrigation control], I1 [Irrigation up to 15 days after transplanting (DAT)], I2 [Irrigation up to 30 ...
متن کاملRoot Canal Irrigation
Irrigation is probably the most underrated procedure in Endodontic therapy. While most articles or presentations spend a great deal of time on shaping procedures, not much emphasis is given for irrigation. This has led to a great deal of confusion on the type of irrigant, the protocol and the method of use. The purpose of this article is to discuss root canal irrigants, irrigation techniques an...
متن کاملControl of shoot and root meristem function by cytokinin.
Plant hormones regulate a variety of processes fundamental for growth and development. Recent studies have clearly shown that establishing adequate spatial and temporal distribution of hormones is central in the control of development. The activity of cytokinins (CKs) is essential to maintain undifferentiated cells in shoot apical meristem (SAM) and to promote cell differentiation in the root m...
متن کاملRoot : shoot ratios, optimization and nitrogen productivity.
Plants respond to nitrogen availability by changing their root : shoot ratios. One hypothesis used to explain this allocation is that plants optimize their behaviour by maximizing their relative growth rate. The consequences of this hypothesis were investigated by formulating two models for root : shoot allocation, with and without explicit inclusion of maintenance respiration. The models also ...
متن کاملEvapotranspiration and yield of okra as affected by partial root-zone furrow irrigation
Partial root-zone drying or partial root-zone irrigation is a newly proposed water saving technique which may improve water use efficiency and nutrient uptake by a crop without affecting its yield. A study was conducted to investigate the response of furrow-irrigated okra to partial root zone drying in relation to cropevapotranspiration (ETc), vegetative growth, yield, and nutrient use effi...
