The purpose of this study is to investigate the distribution characteristics polycyclic aromatic hydrocarbons (PAHs) in Chinese flowering cabbage at different growth stages, and provide reference for people's daily diet production activities. stages were divided into three periods: seedling stage (from first true leaf expansion fifth leaf), sixth appearance plant buds), stem formation buds harv...

We tested the hypothesis that whole-tree water consumption of olives (Olea europaea L.) is fruit load-dependent and investigated the driving physiological mechanisms. Fruit load was manipulated in mature olives grown in weighing-drainage lysimeters. Fruit was thinned or entirely removed from trees at three separate stages of growth: early, mid and late in the season. Tree-scale transpiration, c...

Among seasonal practices that affect grape quality, selective leaf removal at the cluster zone is accepted as a powerful technique to manipulate flavonoid content of grapes and wines. However, most of research on fruit-zone defoliation has been conducted under temperate climate and it remains uncertain if cluster exposure would be a recommendable practice in semiarid viticultural areas. In this...

leaf analysis is a general method of estimating the fertilizer needs in fruit trees, but there exists a limited correlation between it and fruit quality. throughout the present study, fruits were harvested 10 weeks following full bloom and at the commercial maturity (6.2 brix) stages from thirteen different commercial kiwifruit orchards that had been fertilized with different fertilizers, the e...

BACKGROUND AND AIMS Monoecious plants have the capacity to allocate resources separately to male and female functions more easily than hermaphrodites. This can be advantageous against environmental stresses such as leaf herbivory. However, studies showing effects of herbivory on male and female functions and on the interaction with the plant's pollinators are limited, particularly in tropical p...

MADS-domain proteins are important transcription factors involved in many biological processes of plants. In our study, a tomato MADS-box gene, SlFYFL, was isolated. SlFYFL is expressed in all tissues of tomato and significantly higher in mature leave, fruit of different stages, AZ (abscission zone) and sepal. Delayed leaf senescence and fruit ripening, increased storability and longer sepals w...

What causes the domesticated tomato Solanum lycopersicum to have sweet, juicy red fruit and large, compound leaves with narrow-tipped leaflets while its distant wild relative, the Peruvian Solanum pennellii, has small, soapy-smelling green fruit with an unpleasant flavor (Matsui et al., 2007) and small compound leaves with thick, rounded leaflets (see figure)? Thoroughly answering this question...

excessive vegetative growth may bring about improper pollination and consequently lead to reduced fruit set and misshapen fruits. paclobutrazol (pp333) reduces vegetative growth. on the other hand, balanced nutrient uptake at all developmental stages increases fruit quality and yield. an experiment was conducted with the aim of reducing vegetative growth and improving yield of strawberry, selva...
