Genetic analysis of fruit shape traits at different maturation stages in sponge gourd 总被引：5，自引：0，他引：5
The fruit shape is important quantitative trait closely related to the fruit quality. However, the genetic model of fruit shapes has not been proposed. Therefore, in the present study, analysis of genetic effects for fruit shape traits （fruit length and fruit perimeter） in sponge gourd was conducted by employing a developmental genetic model including fruit direct effects and maternal effects. Analysis approaches of unconditional and conditional variances were applied to evaluate the genetic behavior of fruit shape traits at economical and physiological maturation times. The results of variance analysis indicated that fruit length and fruit perimeter were simultaneously affected by fruit direct genetic effects and maternal effects. Fruit direct genetic effects were relatively more important for fruit shape traits at whole developmental period. The gene expression was most active at the economical maturation stage （1-12 d after flowering） for two shape traits, and the activation of gene was mostly due to direct dominance effects at physiological maturation stage （13-60 datter flowering）. The coefficients due to different genetic effects, as well as the phenotypic correlation coefficients, varied significantly between fruit shape traits themselves at various maturation stages. The results showed that it was relatively easy to improve fruit shape traits for industrial purpose by carefully selecting the parents at economical maturation stage instead of that at physiological maturation stage. 相似文献

The serpent was more crafty thanany wild creature that the Lord Godhad made.He said to the woman,“Isit true that God has forbidden youto eat from any tree in the garden?”The woman answered the serpent,“We may eat the fruit of any tree inthe garden,except for the tree inthe middle of the garden;God hasforbidden us either to eat or to touchthe fruit of that;if we do,we shalldie.”The serpent said,“Of courseyou will not … 相似文献

A novel approach for fruit shape detection in RGB space was proposed,which was based on fast level set and Chan-Vese model named as Modified Chan-Vese model(MCV) . This new algorithm is fast and suitable for fruit sorting because it does not need re-initializing. MCV has three advantages compared to the traditional methods. First,it provides a unified frame-work for detecting fruit shape boundary,and does not need any preprocessing even though the raw image is noisy or blurred. Second,if the fruit has different colors at the edges,it can detect perfect boundary. Third,it processed directly in color space without any transformations that may lose much information. The proposed method has been applied to fruit shape detection with promising result. 相似文献

As an advocate for feminism,George Bernard Shaw,to awaken especially women to their subordinate and captivated posi?tion and opportunity for being New woman,wrote Candida in a time when women were stuck into“the virgin mother”role.Howev?er,from the perspective of feminist semiotic theory,we found that although creating a new woman different from the one defined by the common standard,Bernard Shaw still didn’t break the chain of portraying a“sign woman”-“the virgin mother”controlled by the patriarchal prejudice from male gaze.In addition,Candida becomes an object portrayed through two men characters and she be?comes the means to expose the developing of man character rather than the subject in the play.And Shaw’s limited feminism is al?so reflected in his other plays.Therefore,Bernard Shaw is an incomplete feminist. 相似文献

A fox is looking for food. He is hungry and thirsty . He finds a beautiful garden full of fruit and goes in through a hole in the wall. He spends three days in the garden and eats about two- thirds of the fruit. On the fourth day he wants to go home. However, he becomes too fat for the little hole in the wall. He stays in the garden for another three days and during this time he eats nothing. 相似文献

INTRODUCTION Determination of fruit and vegetable quality is very important for both producers and processors. Watermelon as a delicious fruit has been widely ac-cepted in the world and its internal quality is impor-tant for consumers and merchants. The current fa-vorite way for checking a watermelon is to sense sound or vibration by slapping or rapping it. It is time consuming, tedious, and subject to error. Several studies on assessing the quality of watermelon based on its acoustic o… 相似文献

I'll never forget the days I spent in the countryside.When I was seven,my parents sent me to the countryside to live with my grandparents. Around my grandparents' house grew many fruit trees and I used to play in the wood. My grandparents were always telling me not to climb the trees, for they were afraid that I might fall off the trees. But I often climbed up and down the trees secretly, picking fruits. I like eating fruits. Once I asked some children to climb up the trees with a ladder to pick fresh fruit. Now my grandparents didn't seem to mind much. Instead, they smilingly told us to be 相似文献

The apple is the most valuable of all the fruits that grow on trees. It is also more widely grown than any other fruit. Apple trees grow everywhere except in the very hottest and coldest regions of the world. They bear their juicy, crisp fruit in Europe and South America, in Africa and Australia, and in Asia from India northward into Siberia(西伯利亚). Apples are grown in nearly all the states of the Union, and in all the provinces of Canada.Men have grown apple trees for their fruit sinc… 相似文献

INTRODUCTION Recently increasing demands from consumerhave been observed for premium quality fruit witbetter taste at a higher price. Three major parameters determine the internal quality and the tastof apples. These are hardness, sugar content antitratable acidity, which are still determined destructively. Near-infrared spectroscopy (NIRS) habeen used to nondestructively measure internquality in a wide range of fruits and vegetablesuch as onions (Birth et al., 1985), cantaloupe (… 相似文献

In this paper, a novel system using direct contact heat transfer between air and water solution was proposed to generate ice slurry. The heat transfer process and the system performance were studied; energy efficiency coefficients of 0.038, 0.053, and 0.064 were obtained using different solutions. An empirical relationship between the volumetric heat transfer coefficient Uv and the main parameters was obtained by fitting the experimental data. The Uv calculated from the empirical formula agreed with the experimental Uv quite well with a relative error of less than 15%. Based on the empirical formula, a laboratory-scale direct contact ice slurry generator was then constructed, with practical application in mind. If the air flow rate is fixed at 200 m3/h, the ice production rate will be 0.091 kg/min. The experimental results also showed that the cold energy consumption of the air compressor accounted for more than half of the total amount. To improve the system energy efficiency coefficient, it is necessary to increase the air pipes insulation and the solution＇s thermal capacity, and also it is appropriate to utilize the free cold energy of liquefied natural gas （LNG）. 相似文献

(1)Adam' and Eve are being pul out of the beautiful garden of Eden.(2)It is because they did something God told them not to do. God told them they could eat food from the trees of the garden. But from one tree God said not to eat, or else they would die. He kept that tree as his own.(3}One day when Eve was alone in the garden, a snake spoke to her. It told Eve to eat fruit from the tree from which God told them not to eat . Now, when Jehovah made snakes he did not make them so they could talk. So this 相似文献

Through a comparative analysis of The Pilgrim’s Progress and The Journey to the West, the paper aims to reveal what common ground is shared by the two novels and what light is thrown on the theme of spiritual salvation. The fruit of the study leads to a conclusion that both novels have employed religious doctrines and social criticisms to make the theme of spiritual salvation more palatable for their readers. 相似文献

Tens of thousands of baby penguins face starvation after two giant icebergs brokc off the Antarctic ice shect and blocked their parents' access to feeding areas. Adelie and emperor penguins nesting on the Ross Island rookeries are now forced to walk long distances over the icebergs to obtain food for their chicks, born during the November-December breeding season. 相似文献
