Plasticulture studies were continued on bell pepper. Total marketable fruit yields of 4.85, 3.94 and 3.09 tons per acre were obtained from plants grown on silver, white, and black plastic mulches, respectively. Number of fruits produced per plant followed the same trend. Individual fruit weights of 85-117g were not significantly different among treatments. Fruit set as indicated by number of fr...

Despite problems of low fruit set, small fruit size and alternate bearing, the Hass cultivar dominates commercial avocado production worldwide. To increase yield and fruit size, gibberellic acid (GA3) (25 mg L−1) was applied at different stages of ‘Hass’ avocado tree phenology: (i) mid–late April (flower abscission), end of June–beginning of July (fruit abscission and beginning of the exponenti...

The present investigation was carried out during Kharif season at the Horticulture Research centre of Sardar Vallabhbhai Patel University Agriculture & Technology, Meerut, U.P. 2020. D2 statistics applied to assess genetic divergence among 20 genotypes tomato using Mahalonobis analysis. experimental materials were planted in Randomized Block Design (RBD) with three replications. analysis va...

A greenhouse experiment was conducted to investigate the effect of flooding on two tomato cultivars and two wild related species. Forty days old tomato plants were subjected to a continuous flooding stress of different durations: 0, 2, 4 and 8 days. Plant pots were placed inside larger plastic pots; they were irrigated with excessive quantity of tap water at 25C so that the level of water above...

We investigated the effects of plant density on reproductive success for two insect-pollinated plant species—the native North American wildflower Penstemon digitalis (Foxglove-leaved Penstemon), and the showy introduced weed Hesperis matronalis (Dame's Rocket). We found no indication that local density (within 3.0 m) affected reproductive success (seeds per fruit, proportion fruit set, total se...

BACKGROUND AND AIMS It is widely accepted that fruit-set in plants is related to source-sink ratio. Despite its critical importance to yield, prediction of fruit-set remains an ongoing problem in crop models. Functional-structural plant models are potentially able to simulate organ-level plasticity of plants. To predict fruit-set, the quantitative link between source-sink ratio and fruit-set pr...

interspecific hybridization occurs among cucurbia species it is commonly used for grafting, yield increasing and production of pest resistant rootstocks. in the present research probability of interspecies hybrid generation among seven lines of cucurbita pepo (p1, p4, p5, p6, p10, p22, p25) and six lines of cucurbita moschata (mo3, mo5, mo6, mo9, mo11, mo12) were investigated. after crossing of...

Different experiments have showed that interruption in pollination is an important problem in most almond orchards.Asmost of the almond cultivars are self-incompatible,pollination cannot be performed desirably and as a result a failure in almond yield is occurred.Thus under this circumstance,determination of selective cultivars compatibility and choosing appropriate pollinizers are so important...

With SGF Profiling™ we introduce an NMR-based screening method for the quality control of fruit juices. This method has been developed in a joint effort by Bruker BioSpin GmbH and SGF International e.V. The system is fully automated with respect to sample transfer, measurement, data analysis and reporting and is set up on an Avance 400 MHz flow-injection NMR spectrometer. For each fruit juice a...
